The final push to start using Firefox over Chrome on Android might finally be thanks to the enormous selection of add-ons (Firefox’s version of extensions) coming out next month. Chrome doesn’t offer native support for extensions in its mobile app. Also, better security.
If there was one thing Windows Phone and Windows 8 IE did well for mobile devices, it was the bottom orientated address bar.
I’m surprised that it took Android and iOS so long to adapt it; Firefox if i recall correctly adapted to it first in 2014 with an experimental Windows 8 mode that sadly was discontinued.
